meta-palmetto: Update occ sensor object path in ipmid

As openpower-occ-control@1d69e19 introduce the ability to rename the occ
object path, Palmeto could use "occ0" instead of "occ_3_0050" as a
better name.
Update ipmi sensor config to use the updated occ object path.

Tested: Verify occ active sensor is set on host power on, and occ hwmon
        sensors are working OK.
